| 摘 要： | 采用姿控式直接侧向力/气动力复合控制方式可以显著提高大气层内拦截弹的机动能力,但由于产生侧向推力的脉冲发动机数量有限,必须考虑减少使用数量的问题.除了最优化脉冲发动机点火分配逻辑之外,充分利用气动力也是一种可能的方案.本文基于弹体运动的线性化模型,探讨了在给定攻角响应时间的情况下,最大限度地利用气动力能否节省脉冲发动机点火数目,并对攻角响应所需用的脉冲发动机数量做了离线计算,给出了计算公式.

| Abstract: | The maneuver capability of an endoatmospheric interceptor can be significantly improved when its attitude is controlled by lateral impulse thrusters and aerodynamic fins.Means to abate the usage of impulse thrusters must be considered,because the total quantity of the impulse thrusters is limited.Besides the optimization of the fire distribution logic,to extremely make use of aerodynamics may be a possible way.Based on a linearized model of missile motion,the possibility of decreasing the usage of impulse t... |
